In the work reported here conceptual models of high-output systems are considered in which the combustion chamber is visualized as consisting only of a small number of interacting elements composed of homogeneous reaction volumes. Pressure interaction and recirculation are considered. Performance curves developed for four typical models show qualitatively flow interactions and residual flame phenomena typically observed in real combustion chambers. Predicted performance characteristics based on the above models were compared with experimental data obtained in a small combustion chamber burning premixed propane-air mixtures. Stability limits, combustion efficiency-loading rate data, and visual observation of flame and flow were typical measurements made on chamber performance.
